My big Christmas project was a genuine Bûche de Noël, or Yule Log for those of you who didn't have the privilege of having Brother Donan beat French into you.
The French have a tradition of making a rolled cake decorated to look like a log. I saw Jacques Pepin do this last year right before Christmas and I gave it a shot. The cake itself was OK, but the chocolate frosting I made was pretty bad.
This year I used semi-sweet chocolate for the for the frosting instead of bittersweet, and voila!!
